ASSGNOR TO THE TRENTON NEWv RSEY, A CORPORATION OF NEW LAVATORY.

Application filed November The present invention relates to lavatories and has for an object to provide an improved lavatory which will be sanitary in use.

The invention has been developed more particularly in connection with the production of lavatorics made of clay, and in the trade known as china or vitreous china, ot' the l one piece type in which the basin, slab and overflow are incorporated in a unitary structure, and for the purpose of illustrating the principles of the invention. such an emliodiment will be more particularly described, reference being had to the accompanying drawings forming a part hereof and in which* Figure 1 is a central sectional View of a one piece china lavatory embodying the invention,

Figure 2 is a detail view 2-2 of Figure 1, and y n Figure 8 is a central sectional view olia lavatory in which the integral nozzle inlet is omitted. 'A

rlhe lavatory shown in Fig. 1 for the purposes of illustration comprises in one integral structure a basin 5, a slab 6 having a supply nozzle 7 associated therewith, and an overflow passage 8 connected to the basin by an overflow outlet 9 together with a trap 10 below and behind the basin. The overflow outlet 9 is practically concealed beneath the nozzle 7 but easily accessible for cleaning. The inlet leg of the trap is directly in line with and accessible fromthe overt-low passage 8 to facilitate sanitary cleaning` thereof.. The outlet leg of the trap opens to the rear and is arranged to be suitably connected to a waste pipe 12 in the wall behind the basin. The bottom et the basin is formed with the usual outlet 13, which is connected with the trap l0 andthe vertical overllow passage 8 by a horizontal passage 14. The lower wall 15 of this passage is horizontal and parallel to the bottom of the basin and is provided with an aperture 1G in alinement with the outlet 13 to receive a valve fitting 17 carrying a pop u valve 18 whichcontrols the outlet 13. This fitting comprises a cap 18 which, with the washer 19, closes the aperture 16. The valve member 18 comprises a four-wing stem suitably apertured to receive the lower end of the valve operating rod 20 to be lifted thereby. v

which can be readily installed and rtaken on the line 2, 1927. Serial No. 230,452.

Preferably provision is nient of the elective length for which purpose made ior adjustof the valve stem is shown the screw threaded connection 21 between the valve head and the stem. The operating means for lifting the valve is effectively concealed within the structure. As shown 'a valve operating pull rod 20 concealed in the overI'loLw passage 8 is operatively mounted in the opening 22 in the slab and terminates in a convenient knob 23. The fitting by which the rod is mounted within the slab opening may be of any suitable character.y In the arrangement shown for the purposeof illustration, a sleeve 25 is secured in its opening by a nut 26 with a suitable yieldable washer 27 therebeneath. The sleeve carries two oppositely disposed lugs 28, one extending forwardly and one rearwardly which bear against the' underside of the slab. rlhe opening 22 in the slab is enlarged laterally to facilitate assembly of the itting. Then the lugs 28 are turned through ninety degrees from the position shown in Fig. 2, the sleeve may be inserted through the opening.

It' desired the nut 26 and upper end of the sleeve 25 may be cencealed behind an escutcheon 30 which is hcld in position by a suitable nut 31 carried by the upper ond ot the sleeve 25. The rod 20 which is shown as of adjustable length, the two partsbeing suitably threaded together. may be held in adjusted position. by means of a suitable friction spring 33 within the sleeve 25.

The valve operating` rod 20 with its inountings and the valve fitting 17 can be completely removed without interfering with the plumbing connections, and, when these parts are removed, such access may be had to the several waste water passages, including' t 1e inlet leg or' the trap, as to permit thorough cleaning and the maintenance of sanitary conditions.

The lavatory shown in F 3 is generally similar to that shown in Fig. 1 and comprises an integral basin 35 andslab 36. The'overflow passage 38 back of the basin is connected by an overflow outlet 39. Beneath the overflow passage and below and behind the basin a trap 410, the inlet leg of which is directly beneath ar l accessible from the over- [low passage 38 in the structure first described. The outlet leg` oi the trap leads rearwardly and is arranged for connection to the vided with au aperture 46 al ined with the outlet l-B to receive and be Closed by the valve litting 47 Carrying a pop up valve 48. The valve operating pull rod 50 suitably7 1nounted in the slab and extends downwardly lthrough the .overflow passage 38 togoperativel)T engage the waste valve. Y

' In this structure lthe mounting ot the valve pull rod lies relatively close .to the rear wall of the basin sinee space is eeonoinized 'by the absence 'et the integral nozzle shown in the strueture et Fig. '1. ln this structure, as in the structure shown in Fig. l, the inlet leg ot the trap is substantially in alinenife-nt with the opening through the slab and Awith the overflow passage .to 'facilitate Cleaning to maintain sanitary conditions.

The foregoing )articular description is illustrative ii'iei'ely and -is not. intended as delining the lin'iits ot the invention. l
